由于 HTML 解析，我得到了更多详细信息：
Uncaught Error: Template parse errors:
'mat-card-title' is not a known element:
1. If 'mat-card-title' is an Angular component, then verify that it is part of this module.
2. If 'mat-card-title' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("
<mat-card>
<mat-card-header>
[ERROR ->]<mat-card-title>Login</mat-card-title>
</mat-card-header>
<mat-card-content>

更新：
我解决了大部分问题。现在的情况是关于@angular/cdk包：

有什么解决办法吗？谢谢！:)
看到关于这个主题的这些问题：@angular/material/index.d.ts' is not a module , How to import Angular Material in project? ，并按如下方式实现模块，编译器给了我一个错误。
角材料.module.ts
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import {
MatCardModule,
MatDialogModule,
MatMenuModule,
MatButtonModule,
MatToolbarModule,
MatIconModule,
MatBadgeModule,
MatSidenavModule,
MatListModule,
MatGridListModule,
MatFormFieldModule,
MatInputModule,
MatSelectModule,
MatRadioModule,
MatDatepickerModule,
MatNativeDateModule,
MatChipsModule,
MatTooltipModule,
MatTableModule,
MatPaginatorModule,
MatProgressSpinnerModule
} from '@angular/material';
@NgModule({
imports: [
MatCardModule,
MatDialogModule,
MatMenuModule,
MatProgressSpinnerModule,
CommonModule,
MatButtonModule,
MatToolbarModule,
MatIconModule,
MatSidenavModule,
MatBadgeModule,
MatListModule,
MatGridListModule,
MatFormFieldModule,
MatInputModule,
MatSelectModule,
MatRadioModule,
MatDatepickerModule,
MatNativeDateModule,
MatChipsModule,
MatTooltipModule,
MatTableModule,
MatPaginatorModule
],
exports: [
MatCardModule,
MatDialogModule,
MatMenuModule,
MatProgressSpinnerModule,
MatButtonModule,
MatToolbarModule,
MatIconModule,
MatSidenavModule,
MatBadgeModule,
MatListModule,
MatGridListModule,
MatInputModule,
MatFormFieldModule,
MatSelectModule,
MatRadioModule,
MatDatepickerModule,
MatChipsModule,
MatTooltipModule,
MatTableModule,
MatPaginatorModule
],
providers: [
MatDatepickerModule,
]
})
export class AngularMaterialModule { }
最近，在package.json中，我这样添加了一个与 node_modules/@angular/material/index.d.ts 兼容的旧版本：
"dependencies": {
"@angular/animations": "~8.2.14",
"@angular/common": "~8.2.14",
"@angular/compiler": "~8.2.14",
"@angular/core": "~8.2.14",
"@angular/forms": "~8.2.14",
"@angular/material": "^8.2.3",
"@angular/platform-browser": "~8.2.14",
"@angular/platform-browser-dynamic": "~8.2.14",
"@angular/router": "~8.2.14",
"chokidar": "^3.4.2",
"core-js": "^3.6.5",
"rxjs": "~6.4.0",
"tslib": "^1.10.0",
"zone.js": "~0.9.1"
},
最后，在app.module.ts我添加了依赖文件：
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { LoginComponent } from './login/login.component';
import { LogoutComponent } from './logout/logout.component';
import { AngularMaterialModule } from './angular-material.module';
import {HTTP_INTERCEPTORS, HttpClientModule} from '@angular/common/http';
import { HeaderComponent } from './header/header.component';
import { UserComponent } from './user/user.component';
import { FooterComponent } from './footer/footer.component';
import {BasicAuthHtppInterceptorService} from './service/basic-auth-interceptor.service';
我的应用程序结构类似于：
为了在这个版本上显示 HTML 标签，我应该怎么做？
